While driving on the highway, the truck, for an unknown reason, shut down causing me to loose power steering and brake capability. I was able to shift into neutral and turn the key off and then back on again to re-start the truck. It has now happened several times and I have done the same thing each time to correct the problem. It happened once in 2002 then constantly 4-5 times a year and again today. Gm has told me in the past that they don't know what would cause that issue. I could not get my local chevrolet shop manager to give me a straight yes or no answer regarding whether my problem IS consistent with the issues being experienced by effected gm models with ignition problems. I believe it may be due to the recalled ignition switches as I have had the electrical system looked at and no one can seem to find an issue that would cause the truck to shut off randomly at highway speeds and then turn right back over after shifting to neutral!! I believe that the current recall does not cover all of the vehicles that are truly affected. I have had my family in the truck on several occasions when this has happened and have been fortunate to not have had an accident to this point.

I own a 2002 chevy silverado, and I have had the brakes fail on me multiple times the first time I encountered this issue was in early january when I was driving to school and I approached a stop sign and when I went to slow down I had no brakes and my vehicle rolled into the street luckily I wasn't go very fast and there were no cars coming so I didn't get hit. The repairs cost me 175$, that was repairing the problem to bare minimum (single brake line replacement). After I fixed that issue I ran into another problem, the ABS brake system will now spontaneously turn on when I come to a stop, it resulted in a three car crash, I was going to back into a parking spot and when I pulled my truck forward I tried to stop and the ABS locked up my trucks brakes (not slippery out) and forced me to hit two other vehicles, one was majorly damaged and another with minor yet still severe damage, this accident ended with me paying more in insurance and having to fix the damages on my own vehicle out of pocket. I will also in the very near future need to replace all my brake lines because they are on the verge of failing and I am being priced near 900$ for the repairs, I am not sure how much the ABS problem IS going to be because the truck has been parked ever since the incident, the brakes are costing me a lot of money and hardship. *tr

As I was driving I approached a traffic light and applied the brakes. As I applied them, the pedal never offered much resistance and eventually went to the floor. I suspected that a flexible brake line had ruptured so I got off the street as quickly as I could. I examined the inside of all of the wheels where I thought that brake fluid might be evident. There was none to be seen. I limped home with the vehicle and examined it more closely. There was a major leak under the floor of the vehicle in a rigid brake line leading to the anti-lock brake controller. I researched the issue on the internet and found that gm has refused to issue a recall for rusted brake lines. In my opinion these lines should be of the highest quality material to be found. Gm, however, must not think that the safety of their customers warrants any better materials than the rust prone metal that the brake lines are manufactured from. *tr

Traveling on a gravel road @ about 45 mph. Other than being gravel, the road IS very smooth. Heard a loud bang and felt it in the vehicle and in the steering wheel. Found driver's side rear leaf spring rear mounting shackle had broken allowing leaf spring to slam against the bottom of the bed, putting an upward dent in it. Repair mechanic commented the vehicle IS rusted far more than normal. Rails under doors have large 3 inch holes. Rear bumper IS rusted through, the rear tailgate has holes in it. Vehicle only driven to work (2 miles which are gravel) and has very low miles. No one else except silverado owners are experiencing this issue. Very likely inferior design or materials or both. *tr

I own a 2002 chevy silverado 2500 4X4 pickup. My brake lines failed today and caused me to run into a parked car at work. My father has a 1999 chevy silverado 1500 4X4 that he bought brand new and garage kept and still almost had a bad accident due to his brake lines failing 3 years ago. When I gm going to realize that brake lines are not normal wear and tear. I own multiple vintage chevy cars that are between 25 and 37 years old with the original brake lines. Why IS it gm IS waiting for people to be killed due to these problems. I chassis wash my truck as much as possible and also have friends and family with silverados IS year close to mine. All have same issues. Its sad that older gm cars have survived better than these newer built models. Now tomorrow I am going to have to spend alot of money on a part that should not fail. Why IS it that my exhaust system on my car has stainless steel parts but yet the one part that should be absolutely made from stainless steel IS not! Sad that my exhaust will be in great shape as my brake lines fail! I have owned gm cars and truck my whole life and will no longer buy gm products. I have multiple other issues that many, many other silverado owners have. How can thousands of silverados and other make of gm cars and truck have so many of the same problems and gm not recall them. My exhaust manifolds have 2 broken bolts causing an exhaust leak due to broken bolts! I have engines from the 1960's with factory manifolds still installed and no broken bolts. Put the [xxx] american made steel mills back up and stop buying this cheap metal because for what most of us pay for our cars and truck the least gm can do IS put quality parts in them. Offering a brake line kit to have installed in gm dealerships IS not helping people that need there truck like I do daily. Recall the [xxx] brake line problem models and fix them right! *tr information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(B)(6). *tr

On January 11, 2011, ODI opened EA11-001 to investigate allegations of premature brake line corrosion failure in model year (MY) 1999 through 2003 General Motors (GM) full-size pickup trucks and sport utility vehicles sold or registered in the following region of the United States that NHTSA has viewed as salt states for investigations of corrosion related issues:Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin.The subject vehicles represent the first five MY's of GM's GMT800 platform production, of which approximately 2,038,504 vehicles were sold in salt states (the subject vehicles).The GMT800 platform includes the following vehicles:1999-2007 Chevrolet Silverado and GMC Sierra 1500, 2500 and 3500 series pick-up trucks; 2000-2006 Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon sport utility vehicles; and 2002-2006 Cadillac Escalade and Chevrolet Avalanche sport-utility vehicles.General Motors produced a total of approximately 10,427,062 GMT800 vehicles for sales in the United States, including almost 5 million that were sold in salt states.Although there are over 60 different brake pipe routing configuration used in GMT800 vehicles, with the exception of the rear crossover pipes in MY 200x-2007 vehicles that changed from rear disc to drum brakes, all of the vehicles use brake pipes from the same supplier with a common double-wall, brazed steel pipe design with a combination of hot dip Zinc-Aluminum corrosion protection coating and Aluminum paint outer layer known in the industry as AlGal (ASTM-B750). ODI analysis of field data regarding GMT800 vehicles identified a total of 3,645 complaints of brake pipe corrosion failures, including 107 alleging crashes, and 40 injuries.Though only 20% of total GMT800 production, due to age and region the subject vehicles account for a disproportionate share of the failure experience; with 2,702 of the complaints (75%), 88 of the crashes (82%) and 20 of the injuries (50%) reported in those vehicles.Analysis of the complaints showed strong correlations to vehicle age and region.For vehicles with less than 8 years of service, the complaint rates were minimal for all regions.In the salt states the failure rates begin to climb as the vehicles advance in age, particularly in the Northeast corner of the United States.The complaint rates in the salt states go from less than 0.1 incident per thousand vehicles (IPTV) at 7 years in service to over 1.0 IPTV after the 12th year of service for the subject pickup trucks and utility vehicles.Most of the failures reported to ODI occurred in vehicles with more than 10 years in service.ODI?s investigation did not identify any specific defect conditions that were causing or contributing to the brake pipe failures.Nor did the analysis isolate the problem to any subject vehicle sub-populations when analyzed by vehicle type or production range.The investigation found that vehicles experiencing brake pipe corrosion failures were likely to have general patterns of excessive corrosion on the majority of the brake pipe assembly and appear to be occurring due to expected wear out for the brake pipe coating material used in the subject vehicles and the environmental conditions in severe corrosion states.A safety-related defect has not been identified at this time.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will monitor t

The Office of Defects Investigation (ODI) received Defect Petition DP10-003 on March 2, 2010, requesting the investigation of model year (MY) 2003 Chevrolet Silverado 2500HD 4WD pickup trucks for corrosion failures of the vehicle brake lines.DP10-003 was granted and on March 30, 2010, Preliminary Evaluation PE10-010…
The Office of Defects Investigation (ODI) received Defect Petition DP10-003 on March 2, 2010, requesting the investigation of model year (MY) 2003 Chevrolet Silverado 2500HD 4WD pickup trucks for corrosion failures of the vehicle brake lines.DP10-003 was granted and on March 30, 2010, Preliminary Evaluation PE10-010 was opened on more than six million model year 1999 through 2003 light trucks and sport utility vehicles manufactured and sold by General Motors Corporation (GM).On July 2, 2010, ODI received GM's response to an information request, which included GM's assessment of the frequency and safety consequences of the alleged defect. GM stated that:(1) the brake system of the subject vehicles is split front/rear and should a brake pipe suddenly fail for any reason, the affected vehicle would be capable of stopping with the pressure supplied by the remaining circuit; (2) the subject vehicles were designed to meet the hydraulic circuit partial failure requirements of Federal Motor Vehicle Safety Standards 105 and 135, Light Vehicle Brake Systems; and (3) should a brake fluid leak occur for any reason, the brake system malfunction indicator lamp (MIL) would illuminate and warn the driver before the brake fluid level was low enough to cause a loss of line pressure.ODI's and GM's analysis indicates that 85 percent of the complaints occurred on vehicles used primarily in States that use salt on the roads during Winter months (Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin).Overall the complaint rates per 100,000 vehicles for Salt Belt States is 43.0 and Non-Salt Belt is 3.0.In approximately 25 percent of the complaints the brake pipe failure occurred suddenly, with no warning (i.e., no MIL, Brake Fluid Loss Warning), and resulted in extended stopping distances.In 30 of these the increase in stopping distance that resulted was a factor in the crash and in 10 others the vehicle was intentionally steered off the road or into another lane of travel in order to avoid a crash.This investigation has been upgraded to an Engineering Analysis (EA11-001) for subject vehicles sold or currently registered in Salt Belt States to further assess the scope, frequency and safety risks associated with sudden failures of corroded brake pipes that can result in decreased brake effectiveness. ODI will continue to gather information on subject vehicles outside the Salt Belt as well.
- Crank position sensor failure - stall
The office of defects investigation (odi) opened a preliminary evaluation (pe06-016) on may 4, 2006 based on eleven vehicle owner questionnaires (voqs) and early warning (ewr) data alleging sudden engine shutdown while driving as a result of crank position sensor failures in my 2001-2002 general motors c/k platform…
The office of defects investigation (odi) opened a preliminary evaluation (pe06-016) on may 4, 2006 based on eleven vehicle owner questionnaires (voqs) and early warning (ewr) data alleging sudden engine shutdown while driving as a result of crank position sensor failures in my 2001-2002 general motors c/k platform vehicles equipped with 8.1L engines.in response to an information request letter sent by odi, general motors (gm) provided owner complaint information, field reports and warranty claim data based on a population of 108,338 vehicles. The data was categorized by engine stalls while driving, engine stalls with an unknown driving condition, no start conditions and claims where it was indeterminate if an engine stall occurred while driving.general motor's response included 1,213 owner complaints and field reports of which 289 were categorized as engine stalls while driving allegedly caused by crank position sensor failures. General motors also submitted warranty claims from its regular warranty (5 years/50,000 miles) and from its extended warranty database. From the regular warranty database there were 3,140 claims of crank position sensor replacement of which 147 claims were from consumers alleging engine stall while driving.gm stated that 2,841 of the claims were indeterminate if an engine stall occurred while driving.from its extended warranty database, gm submitted 1,561 claims of crank position sensor failure that it also stated were indeterminate as to whether an engine stall occurred while driving.in total, gm reports 4,701 claims of crank position sensor failure combining regular warranty and extended warranty.similar to gm's statistical analysis, odi's analysis showed that the failure rate for warranty claims of engine stall while driving at three years in service IS low (less than 1%).however, further analysis determined that the my 2001 vehicle build period from may 2000 through october 2000 had significantly higher (more than four times) crank position failure rates in both consumer complaint data and warranty claim data than in the build period from november 2000 through july 2001.adding the claims of known engine stall while driving and claims where engine stall was indeterminate, the failure rate at three years in service for this population IS over 6%.AN engineering analysis (ea06-016) has been opened to further assess the frequency and potential safety consequences associated with the alleged defect in vehicles built from may 2000 through october 2000.

In a letter dated august 29, 2005, gm notified odi that it was recalling certain model year 1999 through 2002 c/k pickup trucks and sport utility vehicles to correct a problem with anti-lock brake system (ABS) wheel speed sensor corrosion that may result in unwanted ABS activation and extended stopping distances during low-speed braking (recall 05v-379).gm's recall covers approximately 804,000 vehicles currently registered in the following 14 salt-belt states:connecticut, illinois, indiana, massachusetts, maine, michigan, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, and west virginia.the recall procedure will involve removing the sensor, cleaning the mounting surface, applying a rust inhibitor (zinc-x) to the surface, and reinstalling the sensor.if necessary, the sensor will be replaced. The population and failure report data given in this resume are for the full region that has been considered by odi as the salt-belt.that includes delaware, iowa, maryland, minnesota, missouri, wisconsin and the district of columbia in addition to the 14 states included in 05v-379.the states covered by gm's recall have the highest incident rates for the subject condition, accounting for 91% of the incidents, but only 24% of subject vehicle sales in the united states.odi's analysis determined that 840 of the complaints, 244 of the crashes, and 16 of the injuries identified in this investigation occurred in those states.the resulting incident and crash rates are 96.2 and 28.0 per 100,000 vehicles respectively (note:rates are based on vehicle sales, not registered vehicles). The corresponding numbers in the excluded portions of the salt-belt are 399,000 vehicles, 81 incidents (20.3 per 100,000 vehicles), 3 crashes, and no injuries.the statistics in the remaining 30 states are 2,406,000 vehicles, 168 incidents (7.0 per 100,000 vehicles), 31 crashes, and one injury.gm and odi are continuing to monitor the problem experience in states that are not included in the recall.gm will provide odi with updated complaint, field report, and warranty data in november 2005.odi and gm will review that data and assess the appropriateness of the current scope of the recall at that time.

Odi opened pe03-057 to assess parking brake ineffectiveness in the subject vehicles.these vehicles are equipped with four wheel disc brakes that incorporate a single-shoe drum-in-hat parking brake independent of the service brakes.complaint and warranty data indicate that the parking brake linings tend to wear out early in the life of the vehicle (at an average of 24 months in service), reducing the parking brake system's torque below that needed to immobilize the vehicle.gm has attributed this accelerated wear to foreign material intrusion and a failure of the brake shoe to properly self-center within its brake drum.effective with the start of my 2003 production, a newer reduced force hold-down clip was introduced to facilitate brake shoe disengagement from the drum surface.this part IS also available at the service level for the my 1999-2002 vehicles.gm has indicated that the paking brake IS intended to operate in conjunction with the transmission to immobilze parked vehicles, and that in many cases, accelerated parking brake lining wear IS caused by rough use, vehicle modifications, and driving with the parking engaged. Odi has upgraded the preliminary evaluation to an engineering analysis to gather further information concerning parking brake usage factors and the circumstances surrounding the seventeen reported vehicle crashes.

During the pe, odidiscovered that one or both of the tailgate support cables can break due to the effects of metal fatigue at the point where the cable flexes when the lift gate IS opened and closed. Concurrently, the strength of the cable degrades over time due to corrosion of the wire strands in the support cables.when the vehicle IS stationary and cargo IS being loaded or unloaded, the tailgate can tip downward displacing cargo and/or people to the ground without warning.odi IS also aware of one total separation of the tailgate from the vehicle.owners cannot easily detect whether the support cabes are damaged or corroded because they are covered by a protective sheath.odi IS upgrading this preliminary evaluation for further appropriate action.model year 2003 vehicles will be added to the investigation.further, we will incude additional vehicles, those being the avalanche and cadillac ext, model years 2002-2003, and the sierra, model years 1999-2003.

This investigation involves the general motors corporation (gm)throttle body (tb) utilized in model year (my) 1999-2002 silverado, sierra, tahoe, suburban, avalanche and yukon (subject vehicle(s)) with 4.8L, 5.3L, and 6.0L engines. The tb valve may intermittently stick in a closed position.in such a situation, an operator may apply additional accelerator pedal force to increase engine speed.the application of additional accelerator pedal force, to open a stuck throttle valve, may open the throttle valve more than intended and, in turn, accelerate the engine and vehicle more than intended and reasonably expected by the driver.on august 1, 2002, the office of defects investigation (odi), of the national highway traffic safety administration (nhtsa), opened this engineering analysis.the investigation revealed that two factors may cause the defect: 1) tb manufacturing process problems; and 2) accumulation of deposits (a pcv system by-product) on or around the tb throttle valve and bore.odi concludes that the tb performs in a defective manner after analyzing gm?s data submissions, and test data collected by the vehicle research and test center (vrtc).fifty-nine crashes are alleged to have occurred as a result of gm?s tb defect.the majority of the crashes involve a single vehicle, engaging in a close quarter vehicle maneuver (or low speed), and causing only minor property damage.four out of the fifty-nine crashes involve injury, and those injuries were minor.although gm?s tb IS defective, based on the evidence gathered, odi has found that the accelerator pedal force required to open a stuck throttle valve IS negligible, and the throttle valve does not stick in the open position.therefore this engineering analysis (ea02-015) will be closed at this time.the closing of this investigation does not constitute a finding by nhtsa that a safety-related defect does not exist.for a detailed discussion of the tb component and testing, please see the attached report.
